I have a Toshiba C855D-S530 and an Insignia NS-19E310A13 new TV. I connect through vga cord. The problem is that the tv screen size and resolution keeps changing while I work. It keeps seemingly 'self adjusting' but rather than staying the same - it switches resolution and Screen Size keep changing every 5 to 10 minutes. It cycles between VGA 1024 x 760 x 60HZ and then VGA 1360 x 760 x 60HZ. Sometimes the screen goes black for a few seconds as it changes. Once in awhile a small square appears with “Auto Adjusting” inside the square as it goes through the change.
I've tried windows 8 settings with no sucess in fixing this. I bought an vga to hdmi adapter - and can not even get that to work. I am certain there is something in the tv or the video card of the laptop or in the windows 8 of the laptop causing this annoying issue... but I can not find it. I'd be very grateful for help - especially anyone who solved the issue. Thanks for your time and help!
